1/152. CO 2 laser surgery in hemophilia treatment.

    The use of CO 2 laser surgery between 1985 and 1991 in south africa and portugal for treatment of disorders in patients with mild to moderate cases of hemophilia A is discussed. Six cases of oral procedures and excision of skin tumors performed during this period are reported. In most of the cases of mild hemophilia no pre- or postoperative infusion of factor viii or desmopressin (DDAVP) was required. In some cases of moderate hemophilia, patients were infused with desmopressin (0.3 mug/kg body weight) and were treated postoperatively with the use of nasal desmopressin spray (150 mug to each nostril for four weeks following surgery). factor viii levels were measured before surgery. Follow up of four weeks was uneventful. The mean average power of the CO 2 laser was 20 W continuous and the pulse duration was 0.1 s for ablational procedures. For dermatologic procedures, a flexible plastic CO 2 laser hollow fiber was used (Flexilase, Sharplan, Allandale, NJ). We concluded that CO 2 laser surgery for hemophiliacs has a confirmed place in modern laser technology provided the standard precautions are taken and facilities are available.

2/152. An aggressive and invasive growth of juvenile papillomas involving the total respiratory tract.

    A malignant course of juvenile laryngeal papillomatosis has rarely been reported. In the present case the patient had had laryngeal papillomas since the age of three years. The papillomas gradually spread to the entire respiratory system, and during 30 years the patient was operated on more than 80 times. At present an invasive tumour spreading from the tongue into the parapharyngeal space, extending to the cranial base, has been demonstrated by magnetic resonance imaging (MRI). Intralesional therapy with Cidofovir, a promising antiviral drug against human papillomavirus (HPV) infection, was started with some clinical effect, although only on the superficial tumour growth. histology of removed tumour tissue has demonstrated a mixture of exophytic and inverted growth pattern, and has mainly been interpreted as benign, in spite of a focally high mitotic index and an intermittent lack of maturation in the epithelium. In the most recent biopsies a verrucous carcinoma has been diagnosed. Expression of p53 was noted to increase in papillomas with time. All samples have been shown to harbour HPV 11, but no other HPV types.

3/152. Mucin-producing biliary papillomatosis associated with gastrobiliary fistula.

    We report a case of mucin-producing biliary papillomatosis in a 78-year-old woman. Abdominal ultrasound (US) and computed tomography (CT) showed wall thickening and dilatation of the intrahepatic bile duct (IHBD), as well as a nodular lesion, 1.2 cm in diameter, in the left branch of the IHBD. Gastric endoscopy revealed excretion of bile-containing mucin on the anterior wall of the body of the stomach. Endoscopic ultrasonography (EUS) showed gastrobiliary fistula and discharge of mucin into the stomach. Needle biopsy of the biliary tumor revealed papillary proliferation, but no malignant cells were recognized histologically. Therefore this patient was diagnosed as having mucin-producing biliary papillomatosis forming gastrobiliary fistula. She did not present with obstructive jaundice, probably because of the fistula. She is alive, without obstructive jaundice, 16 months after the diagnosis without having had surgery. This is, to our knowledge, the first reported case of biliary papillomatosis forming gastrobiliary fistula and with the patient free of obstructive jaundice.

4/152. Benefits of stereolithography in orbital reconstruction.

    OBJECTIVE: To describe the benefits of the stereolithography (SLA) modeling system in the evaluation and surgical planning of selected bony orbital pathology. DESIGN: Two case reports. PARTICIPANTS: One patient presented with a displaced left orbital roof fracture into his orbit causing globe compression and binocular vertical diplopia. A second patient underwent removal of his right orbital floor, medial wall, and inferior portion of his lateral wall during excision of a cylindrical cell papilloma of the paranasal sinuses. Postoperatively, he suffered from globe ptosis and binocular oblique diplopia. INTERVENTION: Stereolithographic models of the patients' orbits were obtained from computed tomography data to better assess the bony orbital pathology. In the second patient, the model was used as a template to create a temporary custom fit prosthesis to repair the defect of his orbital walls. RESULTS: The SLA models were useful in evaluating the dimensions of the bony defects and in preoperative surgical planning. Intraoperatively, the SLA models facilitated orbital surgical rehabilitation. Postoperatively, both patients noted resolution of their diplopia after reconstruction of more normal bony anatomy. CONCLUSIONS: In selected cases, SLA offers highly accurate models of the bony orbit for preoperative evaluation, surgical planning, and teaching and can act as a template for custom prosthesis manufacturing. This technology increases the orbital surgeon's options in managing complex orbital pathology.

5/152. Endoscopically assisted anterior cranial skull base resection of sinonasal tumors.

    The traditional approach to sinonasal tumors involving the base of skull has been the anterior craniofacial resection. Endoscopic techniques have created the potential to approach the intranasal aspect of skull base lesions without external incisions and still develop an en bloc resection when removed. We report our initial experience with skull base neoplasms in which the otolaryngic portion of the standard resection was accomplished instead through an endoscopic approach. The nature of lesions favorable for this approach and associated technical issues are discussed. Although we do not consider this approach a replacement for the traditional anterior craniofacial resection, it is an important adjunct in the skull base surgeon's armamentarium.

6/152. Solitary squamous papilloma of the bronchus associated with human papilloma virus type 11.

    A 79-year-old female presented with persistent dry cough, and a chest radiograph showed a mass shadow in the right upper lung. Bronchoscopic examination revealed that the right main bronchus was severely obstructed by a polypoid tumor, which was diagnosed pathologically as squamous papilloma. After the failure of the attempted endobronchial snare to remove the tumor, right upper lobectomy was performed. The polymerase chain reaction (PCR) examination showed the presence of human papilloma virus type 11 dna in the resected tumor, suggesting that this virus was the cause of this solitary squamous papilloma of the lung.

7/152. Laryngeal papillomatosis presenting as acute airway obstruction in a child.

    Upper airway obstruction, regardless of cause, can masquerade or be misdiagnosed as lower airway disease in children. In such cases, therapeutic trials of antibiotics, bronchodilators, and over-the-counter medications for symptom relief routinely fail; however, the original diagnosis often goes unchallenged. If the obstructive process is progressive, then acute occlusion of the airway may occur, rapidly leading to suffocation and death if resuscitation is unsuccessful. Outlined in this report is the case of a young female with a history of asthma, poorly responsive to outpatient treatment, who presented with respiratory arrest. The cause of the respiratory collapse was later identified as a large laryngeal papilloma, a condition rarely encountered by emergency physicians.

8/152. Fine-needle aspiration cytologic diagnosis of intrahepatic biliary papillomatosis (intraductal papillary tumor): report of three cases and comparative study with cholangiocarcinoma.

    Biliary papillomatosis is a rare tumor of the intrahepatic and extrahepatic biliary tree, and its FNA findings have not been reported. The cytologic features of 3 cases of intrahepatic biliary papillomatosis were studied and compared with 5 cases of cholangiocarcinoma. The distinctive features include: 1) hypercellular smear, 2) very broad and often double-cell layered sheets of ductal columnar epithelium, 3) papillary configuration, 4) preserved honeycomb pattern with even nuclear spacing, and 5) dysplastic but not frankly malignant nuclear features. The constellation of these features is highly characteristic of biliary papillomatosis and helpful in distinguishing it from cholangiocarcinoma and other differential diagnoses. A firm preoperative diagnosis can thus be achieved, allowing better planning in management of this borderline malignant tumor.

9/152. Epidermal nevus syndrome with development of a mandibular ameloblastoma.

    Epidermal nevus syndrome (ENS) is a hamartoneoplastic syndrome characterized by the association of epidermal nevi with abnormalities in other organ systems. We report a 32-year-old woman with ENS that, in addition to cutaneous manifestations, showed red plaques on the maxillary and mandibular labial alveolar mucosa and a papillomatous lesion of the midline posterior hard palate. Radiographic examination of the jaws was noncontributory. Approximately 5 years later, a follicular ameloblastoma developed in the mandible. The tumor showed duct-like cystic spaces, continuity with the overlying epithelium, and globular myxomatous areas in the connective tissue. The palatal lesion was diagnosed as papilloma, whereas the maxillary plaques showed nonspecific mucositis. The association of ameloblastoma with ENS is discussed. This is the second case of ENS associated with ameloblastoma reported in the medical literature.

10/152. Giant benign sinonasal squamous papilloma: report of a case.

    We treated a patient with a giant squamous papilloma in the nasal cavity and maxillary sinus that extended through a bony defect into the oral cavity. The mass was excised with a combined endoscopic, Caldwell-Luc, and transoral approach. Lesions of this type are rare, but when they do occur, the rate of recurrence is high. Therefore, long-term followup, including endoscopic examination, is important.
